Duc-Man slightly later than you are looking for , but I went to the 1987 German Grand Prix at Hockenheim . As well as the Grand Prix the supporting races were the Trophae Peugeot 505 Turbo (Saturday 15.00) , EFDA Formula Ford 2000 (Saturday 16.45) , Europacup Renault Elf Turbo for Renault Alpine V6s (Sunday 11.30) , the German Grand Prix (Sunday 14.30) and the ONS Opel Junior Cup , Vauxhall Novas in the U.K. (16.30 Sunday) .

Not a very extensive supporting programme ,although there were demonstrations from the Mercedes Benz Silver Arrows at lunchtime on both Saturday and Sunday and an Air show on Sunday .
